Improvement in wringers



' UNITED i13 MARVIN CALDWELL, OF NORTH EAST, PENNSYLVANIA.

IMPROVEMENT IN WRINGERS.

Specification forming part of Letters Patent No. 193,688, dated July 31,1877; application filed August '28, 1876.

' wringer and its frame-work, so that part of the said frame-work shallserve as standards, to support a vat for water to be used in washing,which is attached solidly thereto, and

also in the arrangement of the operate said wringer.

The device is shown in the accompanying drawings, as follows:

Figure l is an end-view elevation, and Fig. 2 is a side-view elevation.

The parts of the device are as follows: A is the box or vat, whichserves as a tub, in which the washing is done. This is supported on legsB B, which, at the end at which the wringer is used, are so extended asto serve as part of the frame-work of the wringing departs whichvice-that is, they form the uprights of the Wringer. This arrangementgives strength to the frame and to the whole device, and enables me tobetter connect and use the treadle or tension devices.

The parts of the wringer are as follows: J J are the expressing-rollers,which are constructed in the usual manner, and are operated as usual.The tension of these rollers is obtained by the levers Q R, which areconnected together and to a yoke, S, by links q r. The yoke S is formedof a bar and links 8 s, which loop over the upper roller.

The levers are operated by a treadle, P, or by a hand-lever, O, as maybe desired; or both methods may be used on the same machine, which willoften be found convenient, for when the hand-lever is used it can beretained depressed at any point by the ratchet N, and when any extrapressure is wanted it can be given by the foot-lever.

What I claim as my invention, and desire to secure by Letters Patent, isas follows:

1. The combination, in a wringing-machine, of the uprights formed of thelegs B B of the vat A, yoke and links S s s, levers Q R, and links g r,and lever O or P, substantially as shown and described.

2. The combination, in a wringing-machine, ofrollers J J, yoke and linksS s s, levers R and links (1 1', and levers O or P, substa tially as setforth.

In testimony whereof I, the said MARVIN A. CALDWELL, have hereunto setmy hand.
